Scientists find cosmic ripples from birth of universe
Scientists find cosmic ripples from birth of universe
Published March 17, 2014 Astronomers have discovered what they believe is the first direct evidence of the astonishing expansion of the universe in the instant following the Big Bang -- the scientific explanation for the birth of the universe some 13.8 billion years ago. Scientists believe that the universe exploded from a tiny speck and hurled itself out in all directions in the fraction of a second that followed, beginning just 10 to the minus 35 seconds (roughly one trillionth of a trillionth of a trillionth of a second) after the universe's birth. Matter ultimately coalesced hundreds of millions of years later into planets, stars, and ultimately us. And like ripples from a ball kicked into a pond, that Big Bang-fueled expansion caused ripples in the ancient light from that event, light which remains imprinted in the skies in a leftover glow called the cosmic microwave background. Scientists still don’t know who kicked the ball. But if confirmed, the newfound ripples would be amazing proof of what has long been mere theory about what happened in those first millionths of a second. “The implications for this detection stagger the mind,” said Jamie Bock, professor of physics at Caltech, laboratory senior research scientist at the Jet Propulsion Laboratory (JPL) and project co-leader. “We are measuring a signal that comes from the dawn of time.” "It would be the most important discovery since the discovery, I think, that the expansion of the universe is accelerating," Harvard astronomer Avi Loeb, who is not a member of the study team, told Space.com. He compared the finding to a 1998 observation that opened the window on mysterious dark energy and won three researchers the 2011 Nobel Prize in physics. The groundbreaking results came from observations by BICEP2, a telescope at the South Pole, of the cosmic microwave background -- a faint glow left over from the Big Bang. Beginning a fraction of a fraction of a second after the universe's birth, according to the current theory, space-time expanded incredibly rapidly, ballooning outward faster than the speed of light. The afterglow from that expansion is called the cosmic microwave background, and tiny fluctuations in it provide clues to conditions in the early universe. For example, small differences in temperature across the sky show where parts of the universe were denser, eventually condensing into galaxies and galactic clusters. Since the cosmic microwave background is a form of light, it exhibits all the properties of light, including polarization. On Earth, sunlight is scattered by the atmosphere and becomes polarized, which is why polarized sunglasses help reduce glare. In space, the cosmic microwave background was scattered by atoms and electrons and became polarized too. “Our team hunted for a special type of polarization called ‘B-modes,’ which represents a twisting or ‘curl’ pattern in the polarized orientations of the ancient light,” said Bock. The team presented their work at a press conference Monda at Harvard -- the discovery of that characteristic pattern of polarization in the skies, which they called proof of the gravitational waves across the primordial sky. “This work offers new insights into some of our most basic questions: Why do we exist? How did the universe begin? These results are not only a smoking gun for inflation, they also tell us when inflation took place and how powerful the process was,” Harvard theorist Avi Loeb said. |

Why can't the Big Bang be Gods plan? Why can't evolution be Gods plan? Science is based on fact. Religion is based on faith. They are not competing on the same turf.

If you saying everything came out of nothing, how exactly does that work? The Big Bang theory is the biggest magic trick in all of creation if that is what you are saying. But I'm sure you don't believe in "magic" or the supernatural, right? So how did the big bang start? Let me answer this for you--you don't have a friggen clue.

Why? Its a flaw of the human mind that makes us think there has to be patterns and beginnings and ends. This is the way things work on earth. It doesn't mean its that way everywhere.

Because if this is true, its the worst plan in all the universes.

The difference of course being that, over time, science can actually change. Slowly, kicking and screaming the whole time, but it can change. Because as you mention at its core it's based on observation. But, in any case, I would say that they do in many ways compete for the same turf, as you put it. At the end of the day it's all about trying to quantify the universe and our place (if any) in it. |
